Insulin Pumps

An insulin pump is a small computerized device that’s worn continuously and gives insulin through a thin tube placed under the skin. It works all day delivering insulin (basal insulin) and can give extra doses of insulin (bolus) at mealtimes or when your blood glucose (blood sugar) is high.

• Traditional (tubed) pumps: External device with tubing and an infusion set delivering basal and bolus insulin. Enter your blood glucose level and carbohydrate intake in grams and program your insulin dose. May be integrated with your continuous glucose monitor (CGM).
• Patch (tubeless) pumps: Adhesive devices worn on the skin, controlled by an app or device.  These are discreet and easy for active lifestyles.
• Automated insulin delivery (AID) system: AID systems use an insulin pump, CGM, and an algorithm to manage type 1 diabetes by auto-adjusting insulin based on real-time blood glucose levels. 
  
   

Insulin pumps use rapid-acting insulin. This type of insulin starts working quickly and can be delivered in small, steady amounts all day (basal insulin) and in larger amounts at mealtimes or to correct high blood glucose (bolus insulin). 

An insulin pump is a small device that helps manage diabetes by delivering insulin to your body. Some benefits:

• blood glucose management: The pump gives small, steady amounts of insulin all day (basal insulin) and extra doses when you eat or your blood glucose level is high.
• Flexibility: Unlike multiple daily shots, the pump lets you adjust insulin doses easily for meals, exercise, or changes in your routine, like sleeping in or being active.
• Fewer injections: Instead of several shots a day, you only need to insert a small tube (cannula) under your skin every few days, which can be less painful and more convenient.
• Easier to manage activities: You can disconnect the pump for short times (like for swimming and other sports or showering) or use patch pumps that stick to your skin, making it easier to stay active.
• Quality of life: With  less hassle, you may feel like it’s easier to manage your blood glucose.

The insulin in pumps is short-acting so it needs to be worn at all times. You can briefly disconnect for showers, swimming, or certain activities, but you should reconnect immediately afterward.

Most insurance covers pumps as durable medical equipment, but coverage and out-of-pocket costs or copays vary. Check your insurance plan, including medical, pharmacy, and/or durable medical equipment coverage. Your diabetes care team can help with approval and paperwork.
